Hyperfocal distance
24 mm at f/11 on full frame: hyperfocal distance 1.75 m — focus there and everything from 0.87 m to infinity is acceptably sharp.
How the Hyperfocal Distance Calculator works
- Enter focal length and aperture as set on the lens.
- Choose the sensor size, which sets the circle of confusion used in the calculation.
- Focus at the hyperfocal distance, not at infinity — focusing at infinity throws away half your available depth of field.
The method
Hyperfocal distance is the closest focus point at which infinity still appears acceptably sharp, and the near limit is then half that distance.
H = f² / (N x c) + f; near limit = H / 2
24 mm at f/11 with a 0.03 mm circle of confusion: 576 / 0.33 ≈ 1,745 mm, so focus at 1.75 m and everything beyond 0.87 m is sharp.
FAQ
What is the circle of confusion?
The largest blur spot still perceived as a point at normal viewing size. It depends on sensor size and enlargement, which is why the same lens settings give different results on different cameras.
Why not just focus at infinity?
Because acceptable sharpness extends behind the focus point as well as in front, and focusing at infinity wastes all of it. Hyperfocal focusing recovers the near half of the frame.
Is hyperfocal focusing always right for landscapes?
No. It guarantees acceptable sharpness, not maximum sharpness at infinity. If a distant mountain is the subject, focus on the mountain.

Hyperfocal Distance Calculator optimises for acceptable sharpness across the frame — when a distant subject must be critically sharp, focus on it instead.
